Structural load monitoring and performance optimization of Wind Turbines
Fiber Optic Sensing Solutions for the Wind Energy Sector
Wind energy plays a crucial role in the transition to a sustainable future. However, maximizing the efficiency and lifespan of wind turbines requires advanced monitoring and diagnostic capabilities. PhotonFirst's fiber optic sensing solutions provide a significant advantage in this domain, offering unparalleled data accuracy and reliability for critical wind turbine applications.
Why Fiber Optic Sensing (FOS) in Wind Turbines?
EMI-immune
Fiber based sensors are immune to EMI (Electromagnetic Interference) and therefore enable for accurate data collection in the presence of strong electormagnetic fields
low footprint
Multiple sensing points on 1 fiber cable enable comprehensive monitoring of critical components throughout the turbine, including the wings, gearbox, generator and the tower itself.

easier to install
Fiber bases sensors are much smaller than conventional ones and demand for less cabling thanks to multiple sensing points on a single fiber cable.

Key applications of FOS in Wind Turbines
Enhanced Structural Health Monitoring
Blade Monitoring: Fiber optic sensors can be embedded within wind turbine blades to monitor strain, vibration, and temperature. This enables early detection of fatigue, cracks, and other structural issues, allowing for proactive maintenance and extending the lifespan of blades.
Tower Monitoring: Sensors can be integrated into the tower structure to monitor strain and vibration, providing valuable insights into potential structural weaknesses and ensuring the safety and stability of the turbine.
Improved Operational Efficiency
Gearbox Monitoring: Fiber optic sensors can monitor vibrations and temperature within the gearbox, enabling early detection of anomalies that could lead to costly failures
Generator Monitoring: Real-time monitoring of temperature and vibration within the generator can help optimize performance and prevent overheating
Enhanced Safety
Ice Detection: Fiber optic sensors can be used to detect the formation of ice on blades, allowing for timely de-icing procedures and preventing damage to the turbine.
Fire Detection: Fiber optic sensors can be integrated into fire detection systems, providing early warnings and enabling rapid response to emergencies.
